g'nue'ntom Jesse f'alelmz'dw I wariyl'ule wder Patented, Jan. 14,1930 IUNITED STATES PATENT OFFICE v METAL BOOFING-SHINGLE CONSTRUCTIONApplication filed May 18,

This invention relates to improvements in metal roofing shingles, andmore particularl to a novel construction of lock fastenerwhic will bepositioned at the top of each shingle to assist in holding the shingleinplace on the roof, and to positively-prevent water from blowinunderneath the edges of the shingle; An 0 Ject of the invention is toprovide an improved lock fastener for metal roofing shingles, which willbe formed se arately from: the shingles, and will be attac ed to the up-'per edges of the same, in any desired manner, whereby water will beprevented from being blown beneath the edges of said shingles.

.A further object of the invention is to rovide an improved form ofmetal roofing s ingle wlth tongue and groove side edges and aseparatelock fastener; at the top of the shingle which will bepositively en aged by the lower edge'of an upper rowof s ingles toproduce a waterproof joint that will preclude anychance of water fromblowing underneath the same.

A still'further object of the inventions is 4 to provide an improvedlock fastener for met-- a1 roofin shingles, which will be formedseparately rom the shingle, and will lie attachedto the shingle in anydesired manner, and well be adjustable with respect-thereto. I

Other ob'ects will appear as the descriptlon procee s, v In theaccompanying drawings which form a partof my application, I

throughout the following specification and the accompanying drawings todesignate cor.- res onding parts.

' ur'improved metal shingle 1 is preferably formed rectan ular in shape,and is-provided with a longitudinally extending tongue 2, and a spacedlongitudinally extending rib 3 at one'side edgethereof, and alongitudinally extending r1b 4, and a groove ,5 spaced from said rib 4and extending parallel therewith. (:0

The upper or top edges,of the shingles 1 are bent upwardly at rightangles to form a lip 6 which engages andinterlocks with a separatelyformed lock fastener 7 in such a manner that a ortion of the fastenerunderlies the body 0 the shingle and extends upwardly'in contact withtheportion 6 ofthe shingle, and is bent thereover, and downwardly, andalong the upper surface ofthe shingle, terminating in a slightlyupturned lip 8. Thes lock fasteners are 'formed separately from theshingles,- and are attached thereto at their top edges in any desiredmanner by special machinery (not shown). The lower edges of the shinglesare bent downwardl at a slight angle, and then inwardl'y to orm thelocking lips 9, which cooperates with the lips 8 of the lock fasteners7. The under side of the shingles will rest on the upturned portion ofthe lock fastener, and tiereby be automatically, and properly s ace 4The shingles may be attached to the roof in any desire. manner;

It'will be apparent that the, shingles will be self-spacing, andwillreadily interlock with each other to producea metal roof which willpositively prevent the wind or water from blowing underneath theshingles, thereby assuring a waterproof roof which will stand a maximumservice of wear.

The shingles will be laid in courses, from the bottom of the roof to thetop.

As before mentioned,the lock fasteners may be attached to the shinglesby special machinery, but it will be understood that the same, may besecuredthereto by soldering, cementing, welding, or in any desiredmanner. desired, the lock fasteners may be merely clamped to theshingles, thereby permitting 100 of adjustment between theffasteners andshingles if necessary. 5

Many minor changes in detail of construction may be resorted to withoutdeparture from the spirit of the invention.

Having thus described. our invention what we claim as new and desire tosecure by"Let-.

ters Patent of the United States is 1. In a metallic roof construction,the com pination ofa aplurality of metal shingles, havmg upturne lips attheir upper ends and downwardly turned locking lips'at their lower ends,separately formed lock fasteners secured at the top edges .of saidshingles, said fasteners comprising'a lower flange under,- 1

lying the body of the shingle and a loop portion extending upwardly andthen downwardly to embrace'the upturned lip at the 'upper end of theshingle, and an upper'flange contacting with the upper surface of theshingle and provided. at its'free-end with an upturned lip to receivethe lower locking lipof I a shingle in asuperjacent course. 2. In ametallic roof construction, the combination of a plurality of metalshingles having upturned lips at their upper ends and downwardly turnedlocking lips at their low- 1 provided at its to. receive the lowerlockinglip of a shingle -er ends, separately formed lock fasteners se-.

cured at the top edges of said shingles, said fasteners comprising alower flange underlying and contacting the body of the shingle and aloop portion extending upwardly and then downwardly to embrace the upperend of the shingle, and an upper flange contacting with the up orsurface of the shingle and gree end with an upturned'lip in asuperjacent course.
